How to print out the contents of a vector?
...
You can use an iterator:
std::vector<char> path;
// ...
for (std::vector<char>::const_iterator i = path.begin(); i != path.end(); ++i)
std::cout << *i << ' ';
If you want to modify the vector's contents in the for loop, then use iterato...
C# int to byte[]
...
yup. Basically a c++ union implemented as c# structs. This is super-fast and is good for packing and unpacking all kinds of things that don't fit nicely into the bitconverter/endian problem solutions. IIRC, NAudio uses this approach to very good ...
How can I truncate a datetime in SQL Server?
...umbled on this when I tried to truncate a date to the first of the month: SELECT DATEADD( m, 0, DATEDIFF( m, 0, GETDATE( ) ) ) does not work, but SELECT DATEADD( m, DATEDIFF( m, 0, GETDATE( ) ), 0 ) does. At least, this is what I see in 2008R2.

How come an array's address is equal to its value in C?
...rray, not the size of a single element. For example, with code like this:
char array[16];
printf("%p\t%p", (void*)&array, (void*)(&array+1));
We can expect the second pointer to be 16 greater than the first (because it's an array of 16 char's). Since %p typically converts pointers in hexa...

Is there a way to get rid of accents and convert a whole string to regular letters?
...ble" deconstruction
This will separate all of the accent marks from the characters. Then, you just need to compare each character against being a letter and throw out the ones that aren't.
string = string.replaceAll("[^\\p{ASCII}]", "");

What are the advantages of using nullptr?
... be an advantage. But consider the following overloaded functions:
void f(char const *ptr);
void f(int v);
f(NULL); //which function will be called?
Which function will be called? Of course, the intention here is to call f(char const *), but in reality f(int) will be called! That is a big probl...
Regular cast vs. static_cast vs. dynamic_cast [duplicate]
...For example, the C-style cast would allow an integer pointer to point to a char.
char c = 10; // 1 byte
int *p = (int*)&c; // 4 bytes
Since this results in a 4-byte pointer pointing to 1 byte of allocated memory, writing to this pointer will either cause a run-time error or will overwri...
How can I comment a single line in XML?
... parser you are using. Personally, I use an IDE (oXygen) that allows me to select a piece of XML text, right click, and ask to comment it out. Which seems a lot easier than your technique.
